The episode as NWS CRP wrote it up.

NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at Aug 31, 5:51 PM CST, 6 hours 9 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Corpus Christi TX 651 PM CDT Fri Aug 31 2018 .DISCUSSION...See Aviation section for 00Z TAFs. && .AVIATION...Diurnal convection in the waning stages at this time with only isolated activity north of Victoria. Cirrus clouds from earlier convection will remain into the evening for most areas with VFR conditions continuing into the overnight period. The convection will form over the coastal waters overnight and move toward the coast around daybreak. Light winds and high boundary layer moisture could lead to patchy fog for the inland coastal plains around daybreak Saturday with MVFR vsbys. Scattered showers or storms will move into the coastal plains during the morning and drift inland with the sea breeze in the afternoon. MVFR ceilings will be possible with the convection. && .PREVIOUS DISCUSSION... /Issued 417 PM CDT Fri Aug 31 2018/ SHORT TERM (Tonight through Saturday night)... Expect the upper pattern, characterized by an approximate E-W ridge across the SRN CONUS with disturbances moving EWD north of the ridge and with a weak trough approaching the NWRN Gulf of Mexico from the east (GFS/ECMWF deterministic/GFS ensemble mean.) The NAM predicts PWAT values well above normal over the CWA during the period. The copious moisture will continue to contribute to isolated/scattered nocturnal (MSA) and diurnal (MSA/CWA) convection over the region during the period. Maximum Heat Index values Saturday are expected remain around 105F or less over the CWA. LONG TERM (Sunday through Friday)... A combination of a ridge aloft to the east and a broad upper trough over the southwestern half of the U.S., along with a series of disturbances developing over the western Gulf of Mexico will continue to provide rich tropical moisture and increase rainfall potential across South Texas through the period. With PWATs in the 2.0" to 2.2" range, showers and thunderstorms will remain in the forecast through the end of next week. However, at this time deterministic models continue to disagree on both timing and tracking of the disturbances, especially as we head on to the latter half of the week. With this in mind, decided to go more conservative on PoPs (generally 20-30%) towards the end of the period, and used Superblend for a consensus until models come in better agreement. With the increase in cloud cover and rainfall potential for next week, near normal temperatures can be expected, with high temperatures a few degrees cooler than this week. && .PRELIMINARY POINT TEMPS/POPS...
